Speaking for myself this item work perfectly on my 2001 snowpro two place trailer. I did the whole traler over with brand new PT Plywood.I installed these plates right on top of the wood.I like it a lot better that way,If they ever strip again it is so easy to just replace them.And for this price you cannot go wrong.If your looking to do your trailer over the way I did then I would recommend this item.

The plate is 2 inches wide. Aluma trailers have 2 inch aluminum beams running down the center where the crank plate needs to be mounted and doesn't fit if mounted under the trailer. Expect to grind 1/4 inch from each plate for them to fit. Hesitantly recommend because there aren't many other options on the market.
